Assign Block Dates by Classification

We need to be able to use blocked dates but assign which classification(s) it applies too. We have some block dates that are specifically for outside groups only and we still allow our District staff to enter their building use. Example: Summer - we don't allow outside groups to use facilities outside of our IGA partners, but staff still have meetings, etc. There is a classification option when adding a block date, but it is unclear the purpose because unless we give District staff permission to BYPASS BLOCK DATES for any block date, staff cannot enter their requests.
